sudo route add -net 0.0.0.0 gw 192.168.1.1 eth0I have a static network interface, here's what's in /etc/network/interfaces:Here is /etc/network/interfaces:
# This file describes the network interfaces available on your system

dns-nameservers: 192.168.1.7 208.68.220.220 208.67.222.222Any suggestions?
what does ifconfig show after rebooting ie before you manually assign the address etc ?
After reboot check whether network-manager is stated or not.
First, you have commented the line
#auto eth0
Why? So obviously it doesn't start at boot time and you have to manually do it.
Second:
I don't see a route line in your interfaces file.

farzanj: I commented that line out because I get the following error when trying to restart networking:
I have also tried adding the up route add line but that doesn't help either. I'm totally stumped :p

For now just do a work around.
You should have a file:
/etc/rc.d/rc.local
Put these two lines in that file and everything should work.
ifconfig eth0 up 192.168.1.137 netmask 255.255.255.0
route add -net 0.0.0.0 gw 192.168.1.1 eth0
You should have a file:
/etc/rc.d/rc.local
Put these two lines in that file and everything should work.
ifconfig eth0 up 192.168.1.137 netmask 255.255.255.0
route add -net 0.0.0.0 gw 192.168.1.1 eth0
Ok. The file in Ubuntu may be
/etc/init.d/local
Make sure it starts with
#!/bin/sh
And it is executable
ls -l /etc/init.d/local
/etc/init.d/local
Make sure it starts with

ls -l /etc/init.d/local

network-manager is running, however when I click on 'Connection Information' it pops up an error window
Error displaying connection information:
No valid active connections found.
And when I open 'Edit Connections' it always says 'Never' under last used column by Eth0
